A limitation of current cancer care is the difficulty of quickly assessing how well a therapy is working. However, expanding the use of existing positron emission tomography (PET) technology can provide early and accurate assessment of a tumors response to a particular therapy allowing physicians to better tailor a patients treatment, according to Malik Juweid, M.D., associate professor of radiology at the University of Iowa Roy J. and Lucille A. Carver College of Medicine.
Writing in the Feb. 2 issue of the New England Journal of Medicine, Juweid and co-author Bruce Cheson, M.D., of the Lombardi Comprehensive Cancer Center at Georgetown University Hospital, outline the advantages and limitations of PET imaging in assessing cancer therapy and suggest that increasing the role of PET imaging has the potential to further improve cancer care management.
PET is a non-invasive imaging technique that uses radioactivity emitted from injected tracer chemicals to measure and image biological activity. The most commonly used PET radiotracer is fluorodeoxyglucose (FDG), a radiolabeled form of glucose, which is consumed more avidly by tumors than by normal tissue.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
